FIELD OF THE INVENTION

This invention relates generally to modulators of chemokine receptor activity, pharmaceutical compositions containing the same, and methods of using the same as agents for treatment and prevention of inflammatory diseases, allergic and autoimmune diseases, and in particular, rheumatoid arthritis and transplant rejection.

BACKGROUND OF THE INVENTION

Chemokines are chemotactic cytokines, of molecular weight 6-15 kDa, that are released by a wide variety of cells to attract and activate, among other cell types, macrophages, T and B lymphocytes, eosinophils, basophils and neutrophils (reviewed in: Luster, New Eng J. Med. 1998, 338, 436-445 and Rollins, Blood 1997, 90, 909-928). There are two major classes of chemokines, CXC and CC, depending on whether the first two cysteines in the amino acid sequence are separated by a single amino acid (CXC) or are adjacent (CC). The CXC chemokines, such as interleukin-8 (IL-8), neutrophil-activating protein-2 (NAP-2) and melanoma growth stimulatory activity protein (MGSA) are chemotactic primarily for neutrophils and T lymphocytes, whereas the CC chemokines, such as RANTES, MIP-1α, MIP-1β, the monocyte chemotactic proteins (MCP-1, MCP-2, MCP-3, MCP-4, and MCP-5) and the eotaxins (-1 and -2) are chemotactic for, among other cell types, macrophages, T lymphocytes, eosinophils, dendritic cells, and basophils. There also exist the chemokines lymphotactin-1, lymphotactin-2 (both C chemokines), and fractalkine (a CX₃C chemokine) that do not fall into either of the major chemokine subfamilies.

The chemokines bind to specific cell-surface receptors belonging to the family of G-protein-coupled seven-transmembrane-domain proteins (reviewed in: Horuk, Trends Pharm. Sci. 1994, 15, 159-165) which are termed “chemokine receptors.” On binding their cognate ligands, chemokine receptors transduce an intracellular signal though the associated trimeric G proteins, resulting in, among other responses, a rapid increase in intracellular calcium concentration, changes in cell shape, increased expression of cellular adhesion molecules, degranulation, and promotion of cell migration. There are at least ten human chemokine receptors that bind or respond to CC chemokines with the following characteristic patterns (reviewed in Zlotnik and Oshie Immunity 2000, 12, 121): CCR-1 (or “CKR-1” or “CC-CKR-1”) [MIP-1α, MCP-3, MCP-4, RANTES] (Ben-Barruch, et al., Cell 1993, 72, 415-425, and Luster, New Eng. J. Med. 1998, 338, 436-445); CCR-2A and CCR-2B (or “CKR-2A”/“CKR-2B” or “CC-CKR-2A”/“CC-CKR-2B”) [MCP-1, MCP-2, MCP-3, MCP-4, MCP-5] (Charo, et al., Proc. Natl. Acad. Sci. USA 1994, 91, 2752-2756, and Luster, New Eng J. Med. 1998, 338, 436-445); CCR-3 (or “CKR-3” or “CC-CKR-3”) [eotaxin-1, eotaxin-2, RANTES, MCP-3, MCP-4] (Combadiere, et al., J. Biol. Chem. 1995, 270, 16491-16494, and Luster, New Eng J. Med. 1998, 338, 436-445); CCR-4 (or “CKR-4” or “CC-CKR-4”) [TARC, MDC] (Power, et al., J. Biol. Chem. 1995, 270, 19495-19500, and Luster, New Eng. J. Med. 1998, 338, 436-445); CCR-5 (or “CKR-5” OR “CC-CKR-5”) [MIP-1α, RANTES, MIP-1β] (Sanson, et al., Biochemistry 1996, 35, 3362-3367); CCR-6 (or “CKR-6” or “CC-CKR-6”) [LARC] (Baba, et al., J. Biol. Chem. 1997, 272, 14893-14898); CCR-7 (or “CKR-7” or “CC-CKR-7”) [ELC] (Yoshie et al., J. Leukoc. Biol. 1997, 62, 634-644); CCR-8 (or “CKR-8” or “CC-CKR-8”) [I-309] (Napolitano et al., J. Immunol., 1996, 157, 2759-2763); CCR-10 (or “CKR-10” or “CC-CKR-10”) [MCP-1, MCP-3] (Bonini, et al., DNA and Cell Biol. 1997, 16, 1249-1256); and CCR-11 [MCP-1, MCP-2, and MCP-4] (Schweickert, et al., J. Biol. Chem. 2000, 275, 90550).

In addition to the mammalian chemokine receptors, mammalian cytomegaloviruses, herpesviruses and poxviruses have been shown to express, in infected cells, proteins with the binding properties of chemokine receptors (reviewed in: Wells and Schwartz, Curr. Opin. Biotech. 1997, 8, 741-748). Human CC chemokines, such as RANTES and MCP-3, can cause rapid mobilization of calcium via these virally encoded receptors. Receptor expression may be permissive for infection by allowing for the subversion of normal immune system surveillance and response to infection. Additionally, human chemokine receptors, such as CXCR4, CCR2, CCR3, CCR5 and CCR8, can act as co-receptors for the infection of mammalian cells by microbes as with, for example, the human immunodeficiency viruses (HIV).

The chemokines and their cognate receptors have been implicated as being important mediators of inflammatory, infectious, and immunoregulatory disorders and diseases, including asthma and allergic diseases, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis (reviewed in: P. H. Carter, Current Opinion in Chemical Biology 2002, 6, 510; Trivedi, et al, Ann. Reports Med. Chem. 2000, 35, 191; Saunders and Tarby, Drug Disc. Today 1999, 4, 80; Premack and Schall, Nature Medicine 1996, 2, 1174). For example, the chemokine macrophage inflammatory protein-1 (MIP-1α) and its receptor CC Chemokine Receptor 1 (CCR-1) play a pivotal role in attracting leukocytes to sites of inflammation and in subsequently activating these cells. When the chemokine MIP-1α binds to CCR-1, it induces a rapid increase in intracellular calcium concentration, increased expression of cellular adhesion molecules, cellular degranulation, and the promotion of leukocyte migration.

In addition, demonstration of the chemotactic properties of MIP-1α in humans has been provided experimentally. Human subjects, when injected intradermally with MIP-1α experienced a rapid and significant influx of leukocytes to the site of injection (Brummet, M. E. J. Immun. 2000, 164, 3392-3401).

Demonstration of the importance of the MIP-1α/CCR-1 interaction has been provided by experiments with genetically modified mice. MIP-1α −/− mice had normal numbers of leukocytes, but were unable to recruit monocytes into sites of viral inflammation after immune challenge (Cook, D., et al., Science. 1995, 269, 1583-1585). Recently, MIP-1α −/− mice were shown to be resistant to collagen antibody induced arthritis (Chintalacharuvu, S. R. Immun. Lett. 2005, 202-204). Likewise, CCR-1 −/− mice were unable to recruit neutrophils when challenged with MIP-1α in vivo; moreover, the peripheral blood neutrophils of CCR-1 null mice did not migrate in response to MIP-1α (Gao, B. et al. J. Exp. Med. 1997, 185, 1959-1968), thereby demonstrating the specificity of the MIP-1α/CCR-1 interaction. The viability and generally normal health of the MIP-1α −/− and CCR-1 −/− animals is noteworthy, in that disruption of the MIP-1α/CCR-1 interaction does not induce physiological crisis. Taken together, these data lead one to the conclusion that molecules that block the actions of MIP-1α would be useful in treating a number of inflammatory and autoimmune disorders. This hypothesis has now been validated in a number of different animal disease models, as described below.

It is known that MIP-1α is elevated in the synovial fluid and blood of patients with rheumatoid arthritis (Alisa Koch, et al., J. Clin. Invest. 1994, 93, 921-928). Moreover, several studies have demonstrated the potential therapeutic value of antagonism of the MIP-1α/CCR1 interaction in treating rheumatoid arthritis (Pease, J. E. & Horuk, R. Expert Opin. Invest. Drugs 2005, 14, 785-796).

An antibody to MIP-1α was shown to ameliorate experimental autoimmune encepahlomytis (EAE), a model of multiple sclerosis, in mice (Karpus, W. J., et al., J. Immun. 1995, 5003-5010). Likewise, inflammatory disease symptoms could be controlled via direct administration of antibodies for MIP-1α to mice with collagen-induced arthritis (Lukacs, N. W., et al., J. Clin. Invest. 1995, 95, 2868-2876).

It should also be noted that CCR-1 is also the receptor for the chemokines RANTES, MCP-3, HCC-1, Lkn-1/HCC-2, HCC-4, and MPIF-1 (Carter, P. H. Curr. Opin Chem. Bio. 2002, 6, 510-525). Since it is presumed that the new compounds of the present invention described herein antagonize MIP-1α by binding to the CCR-1 receptor, it may be that these compounds are also effective antagonists of the actions of the aforementioned ligand that are mediated by CCR-1. Accordingly, when reference is made herein to “antagonism of MIP-1α,” it is to be assumed that this is equivalent to “antagonism of chemokine stimulation of CCR-1.”

For example, demonstration of the chemotactic properties of RANTES in humans has been provided experimentally. Human subjects, when injected intradermally with RANTES, experienced an influx of eosinophils to the site of injection (Beck, L. A. et al. J. Immun. 1997, 159, 2962-2972). Likewise, a RANTES antibody has demonstrated the ability to ameliorate the symptoms of disease in the rat Adjuvant induced arthritis (AIA) model (Barnes, D. A. et al. J. Clin Invest. 1998, 101, 2910-2919). Similar results were obtained when using a peptide derived antagonist of the RANTES/CCR-1 interaction in both the rat AIA (Shahrara, S. et al. Arthritis & Rheum. 2005, 52, 1907-1919) and the mouse CIA (Plater-Zyberk, C. et al. Imm. Lett. 1997, 57, 117-120) disease models of joint inflammation.

Recently, a number of groups have described the development of small molecule antagonists of MIP-1α (reviewed in: Carson, K. G., et al, Ann. Reports Med. Chem. 2004, 39, 149-158).

The invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. This invention also encompasses all combinations of alternative aspects of the invention noted herein. It is understood that any and all embodiments of the present invention may be taken in conjunction with any other embodiment to describe additional embodiments of the present invention. Furthermore, any elements of an embodiment may be combined with any and all other elements from any of the embodiments to describe additional embodiments.

DEFINITIONS

The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.

One enantiomer of a compound of The present invention may display superior activity compared with the other. Thus, all of the stereochemistries are considered to be a part of the present invention. When required, separation of the racemic material can be achieved by HPLC using a chiral column or by a resolution using a resolving agent such as camphonic chloride as in Steven D. Young, et al, Antimicrobial Agents and Chemotheraphy, 1995, 2602-2605.

The term “substituted,” as used herein, means that any one or more hydrogens on the designated atom or ring is replaced with a selection from the indicated group, provided that the designated atom's or ring atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced.

When any variable (e.g., R₄) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with (R₄)_(m) and m is 0-3, then said group may optionally be substituted with up to three R₄ groups and R₄ at each occurrence is selected independently from the definition of R₄. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

In addition, compounds of the present invention are, subsequent to their preparation, preferably isolated and purified to obtain a composition containing an amount by weight equal to or greater than 99% of the compound (“substantially pure” compound), which is then used or formulated as described herein. Such “substantially pure” compounds of the present invention are also contemplated herein as part of the present invention.

All stereoisomers of the compounds of the instant invention are contemplated, either in admixture or in pure or substantially pure form. The compounds of the present invention can have asymmetric centers at any of the carbon atoms including any one of the R substituents and/or exhibit polymorphism. Consequently, compounds of the present invention can exist in enantiomeric, or diastereomeric forms, or in mixtures thereof. The processes for preparation can utilize racemates, enantiomers, or diastereomers as starting materials. When diastereomeric or enantiomeric products are prepared, they can be separated by conventional methods for example, chromatographic or fractional crystallization.

“Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. The present invention is intended to embody stable compounds.

“Therapeutically effective amount” is intended to include an amount of a compound of the present invention alone or an amount of the combination of compounds claimed or an amount of a compound of the present invention in combination with other active ingredients effective to inhibit MIP-1α or effective to treat or prevent inflammatory disorders.

As used herein, “treating” or “treatment” cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) preventing the disease-state from occurring in a mammal, in particular, when such mammal is predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, i.e., arresting it development; and/or (c) relieving the disease-state, i.e., causing regression of the disease state.

Synthesis

The compounds of the present invention can be prepared in a number of ways well known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. All references cited herein are hereby incorporated in their entirety herein by reference.

The novel compounds of this invention may be prepared using the reactions and techniques described in this section. The reactions are performed in solvents appropriate to the reagents and materials employed and are suitable for the transformations being effected. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and work up procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reactions proposed. Such restrictions to the substituents that are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Third Edition, Wiley and Sons, 1999).

Chemokine receptor antagonists of the present invention can be prepared from the protected amino acid derivative 1.1 by coupling with a piperidine 1.2 under standard amide bond forming conditions to yield 1.3 as shown in Scheme 1. Deprotection of the nitrogen can provide an amine 1.4 which can be reacted further with derivatizing reagents to provide (I & Ia). Additionally, protected amino acid derivatives, such as 1.5, can be reacted with a substituted piperidine 1.6, and further transformed to compounds of the invention Ib and Ib′ using a similar sequence as in the preparation of I.

Alternatively, compounds of the present invention can be synthesized as shown in Scheme 2. Coupling of the functionalized amino acid derivative 2.1 with piperidine 1.2 or 1.6 under standard amide bond forming conditions can provide compound I and Ia, (A) or Ib and Ib′ (B).

Hydroxypiperidine and dihydropiperidine analogs can be prepared according to the methods outlined in Scheme 3. The functionalized acid 2.1 can be coupled to the hydroxy piperidine 3.1 to furnish 3.2, which in itself can be used as a chemokine inhibitor. Elimination of the hydroxyl group under acidic conditions can yield dihydropiperidines of the present invention.

A resin supported synthesis can also be employed using the reactions outlined in Scheme 4. Coupling of an amine ester to a properly functionalized resin can give 4.1 which upon amine functionalization can form 4.2. Standard saponification can yield the pendant acid derivatized resin 4.3. Amide bond formation with amine 1.2 or 3.1 can furnish analogs 4.4 and 4.5, respectively. Removal from the resin using acid can furnish the dihydropiperidine (Ie) from hydroxypiperidine 4.5 and the piperidine (I & Ia) from 4.4.

Compounds of the invention can also be prepared according to the methods outlined in Scheme 5. An appropriately functionalized amine 1.4 can be reacted with an isothiocyanate followed by alkylation in the presence of a base with iodomethane to furnish 5.1. Compound 5.1 can be further reacted with, for example a hydrazine or a hydroxylamine derivative, to furnish the substituted triazole or the oxadiazole of the present invention.

Furthermore, compounds of the present invention can be prepared by reaction compound 6.1 with an appropriate acid containing a displaceable leaving group, such as bromine to give compound 6.2. Compound 6.2 can be reacted with an amine in an appropriate solvent to furnish compounds of the present invention.

Alternatively, compounds of the present invention can be synthesized as shown in Schemes 7a and 7b. Reacting a properly functionalized analog of compounds of the present invention under a variety of conditions known to those skilled in the art can provide additional compounds of the present invention. It is to be assumed that the examples shown in Schemes 7a and 7b are merely representative of a variety of transformations and interconversions of functionality that are possible with the knowledge of one skilled in the art of organic synthesis.

Additional compounds of the present invention can be prepared according to the methods in Scheme 8. Compound 8.1 can be reacted with an aryl halide or hereroaryl halide to give the appropriately substituted amine. Furthermore, compound 8.1 could be reacted with an anhydride to provide the amide or reacted with a haloacetyl halide, such as chloroacetyl chloride, followed by a nucleophile, such as pyrazole to give the substituted amide.

Additional compounds of the present invention can also be prepared according to the methods outlined in Scheme 9. An amino acid, such as D-valine (9.1), can be reacted with an aryl halide, such as -iodobenzene to give the N-aryl amino acid 9.2. This amino acid can then be reacted with an appropriately substituted piperidine, such as 9.3 to provide compounds of the invention of the general formula (Id).

Other features of the invention will become apparent in the course of the following descriptions of exemplary embodiments that are given for illustration of the invention and are not intended to be limiting thereof.

UTILITY

In general, compounds of the present invention, such as particular compounds disclosed in the preceding examples, have been shown to be modulators of chemokine receptor activity at concentrations equivalent to, or more potently than, 20 μM, preferably 10 μM, more preferably 5 μM. By displaying activity at these concentrations, compounds of the present invention are expected to be useful in the treatment of human diseases associated with chemokines and their cognate receptors. Potencies can be calculated and expressed as either inhibition constants (Ki values) or as IC₅₀ values, and refer to activity measured employing the assay system(s) described below.

Antagonism of MIP-1α Binding to Human THP-1 Cells (Yoshimura et al., J. Immunol., 1990, 145, 292)

Compounds of the present invention have activity in the antagonism of MIP-1α binding to human THP-1 cells described here.

Millipore filter plates (#MABVN1250) are treated with 100 μl of binding buffer (0.5% bovine serum albumin, 20 mM HEPES buffer and 5 mM magnesium chloride in RPMI 1640 media) for thirty minutes at room temperature. To measure binding, 50 μl of binding buffer, with or without a known concentration of compound, is combined with 50 μl of ¹²⁵-I labeled human MIP-1α (to give a final concentration of 50 pM radioligand) and 50 μl of binding buffer containing 5×10⁵ cells. Cells used for such binding assays can include the THP-1 cell line, which expresses the endogenous CCR1 receptor, or human peripheral blood mononuclear cells, isolated by Ficoll-Hypaque gradient centrifugation, or human monocytes (Weiner et al., J. Immunol. Methods, 1980, 36, 89). The mixture of compound, cells and radioligand is incubated at room temperature for thirty minutes. Plates are placed onto a vacuum manifold, vacuum applied, and the plates washed three times with binding buffer containing 0.5M NaCl. The plastic skirt is removed from the plate, the plate allowed to air dry, the wells punched out and counted. The percent inhibition of binding is calculated using the total counts obtained in the absence of any competing compound and the background binding determined by addition of 100 nM MIP-1α in place of the test compound.

Antagonism of MIP-1α-induced Calcium Influx (Sullivan et al., Methods Mol. Biol., 114, 125-133 (1999)

Compounds of the present invention have activity in the antagonism of MIP-1α-induced calcium influx assay described here.

Calcium mobilization is measured using the fluorescent Ca²⁺ indicator dye, fluo-3. Cells used can include cell lines that express the endogenous CCR1 receptor such as MonoMac-6 cells and THP-1 cells, or freshly obtained human monocytes isolated as described by Weiner et al., J. Immunol. Methods, 36, 89-97 (1980). The cells are incubated at 8×10⁵ cells/mL in phosphate-buffered saline containing 0.1% bovine serum albumin, 20 mM HEPES buffer, 5 mM glucose, 1% fetal bovine serum, 4 μM fluo-3 AM and 2.5 mM probenecid for 60 minutes at 37° C. After washing three times in phosphate-buffered saline containing 0.1% bovine serum albumin, 20 mM HEPES, 5 mM glucose and 2.5 mM probenecid, the cells are resuspended in phosphate-buffered saline containing 0.5% bovine serum albumin, 20 mM HEPES and 2.5 mM probenecid at a final concentration of 2-4×10⁶ cells/mL. Cells are plated into 96-well, black-wall microplates (100 μl/well) and the plates centrifuged at 200×g for 5 minutes. Various graded concentrations of compound are added to the wells (50 μl/well) and after 5 minutes, 50 μl/well of MIP-1α is added to give a final concentration of 10 nM. Calcium mobilization occurs immediately after addition of ligand and is detected using a fluorescent-imaging plate reader, utilizing an argon laser (488 nm). Cell-associated fluorescence is measured for 3 minutes (every second for the first 90 seconds and every 10 seconds for the next 90 seconds). Data are generated as arbitrary fluorescence units and the change in fluorescence for each well determined as the maximum-minimum differential. Compound-dependent inhibition is calculated relative to the response of MIP-1α alone.

Antagonism of MIP-1α-Induced THP-1 Cells Chemotaxis

Compounds of the present invention have activity in the antagonism of MIP-1α-induced THP-1 cells chemotaxis assay described here.

BD Falcon HTX Fluoroblok 96-Multiwell Insert System plates (8 micron, catalog #351164) are warmed in a 37° C. incubator. After centrifugation, THP-1 cells (1.5×10⁷ cells per plate) are resuspended in 1 mL of RPMI 1640 medium (without phenol red). 5 μl of 1 mg/mL calcein-AM (Molecular Probes catalog #C-3100) are added to the cell suspension. After mixing gently, the cells are incubated at 37° C. for 30 minutes. 14 mL of RPMI 1640 (with 0.1% BSA) are added and the cells centrifuged at 1300 rpm for 5 minutes. The pellet is resuspended in 7.5 mL of pre-warmed RPMI 1640 (with 0.1% BSA). A 20 nM solution of human MIP-1α is also warmed at 37° C. Compounds are diluted in RPMI 1640 to give concentrations twice the final values. The THP-1 cell suspension and the 20 nM MIP-1α solution are mixed 1:1 in polypropylene tubes with pre-warmed RPMI with or without a dilution of the test compounds. These mixtures are warmed in a 37° C. tube warmer. 50 μl of the cell suspension+compound are added to each of the insert wells. 225 μl of MIP-1α+compound are added to the lower reservoirs of the BD-Falcon Fluoroblok. The Fluoroblok plate is placed in a 37° C. incubator, incubated for 60 minutes and read in a Cytofluor II Fluorescence Multi-Well Plate Reader (PerSeptive Biosystems, Inc.) under instrumental settings of excitation wavelength at 485 nm and detection wavelength at 530 nm. Data are generated as arbitrary fluorescence units and the change in fluorescence for each well determined as the maximum-background differential. Compound-dependent inhibition is calculated relative to the response of MIP-1α alone.

Mammalian chemokine receptors provide a target for interfering with or promoting immune cell function in a mammal, such as a human. Compounds that inhibit or promote chemokine receptor function are particularly useful for modulating immune cell function for therapeutic purposes.

Accordingly, the present invention is directed to compounds which are useful in the prevention and/or treatment of a wide variety of inflammatory, infectious, and immunoregulatory disorders and diseases, including asthma and allergic diseases, infection by pathogenic microbes (which, by definition, includes viruses), as well as autoimmune pathologies such as the rheumatoid arthritis and atherosclerosis.

For example, an instant compound which inhibits one or more functions of a mammalian chemokine receptor (e.g., a human chemokine receptor) may be administered to inhibit (i.e., reduce or prevent) inflammation or infectious disease. As a result, one or more inflammatory process, such as leukocyte emigration, adhesion, chemotaxis, exocytosis (e.g., of enzymes, histamine) or inflammatory mediator release, is inhibited.

Similarly, an instant compound which promotes one or more functions of the mammalian chemokine receptor (e.g., a human chemokine) as administered to stimulate (induce or enhance) an immune or inflammatory response, such as leukocyte emigration, adhesion, chemotaxis, exocytosis (e.g., of enzymes, histamine) or inflammatory mediator release, resulting in the beneficial stimulation of inflammatory processes. For example, eosinophils can be recruited to combat parasitic infections. In addition, treatment of the aforementioned inflammatory, allergic and autoimmune diseases can also be contemplated for an instant compound which promotes one or more functions of the mammalian chemokine receptor if one contemplates the delivery of sufficient compound to cause the loss of receptor expression on cells through the induction of chemokine receptor internalization or the delivery of compound in a manner that results in the misdirection of the migration of cells.

In addition to primates, such as humans, a variety of other mammals can be treated according to the method of the present invention. For instance, mammals, including but not limited to, cows, sheep, goats, horses, dogs, cats, guinea pigs, rats or other bovine, ovine, equine, canine, feline, rodent or murine species can be treated. However, the method can also be practiced in other species, such as avian species. The subject treated in the methods above is a mammal, male or female, in whom modulation of chemokine receptor activity is desired. “Modulation” as used herein is intended to encompass antagonism, agonism, partial antagonism and/or partial agonism.

Diseases or conditions of human or other species which can be treated with inhibitors of chemokine receptor function, include, but are not limited to: inflammatory or allergic diseases and conditions, including respiratory allergic diseases such as asthma, allergic rhinitis, hypersensitivity lung diseases, hypersensitivity pneumonitis, eosinophilic cellulitis (e.g., Well's syndrome), eosinophilic pneumonias (e.g., Loeffler's syndrome, chronic eosinophilic pneumonia), eosinophilic fasciitis (e.g., Shulman's syndrome), delayed-type hypersensitivity, interstitial lung diseases (ILD) (e.g., idiopathic pulmonary fibrosis, or ILD associated with rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, systemic sclerosis, Sjogren's syndrome, polymyositis or dermatomyositis); systemic anaphylaxis or hypersensitivity responses, drug allergies (e.g., to penicillin, cephalosporins), eosinophilia-myalgia syndrome due to the ingestion of contaminated tryptophan, insect sting allergies; autoimmune diseases, such as rheumatoid arthritis, psoriatic arthritis, multiple sclerosis, systemic lupus erythematosus, myasthenia gravis, juvenile onset diabetes; glomerulonephritis, autoimmune thyroiditis, Behcet's disease; graft rejection (e.g., in transplantation), including allograft rejection or graft-versus-host disease; inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis; spondyloarthropathies; scleroderma; psoriasis (including T-cell mediated psoriasis) and inflammatory dermatoses such as an dermatitis, eczema, atopic dermatitis, allergic contact dermatitis, urticaria; vasculitis (e.g., necrotizing, cutaneous, and hypersensitivity vasculitis); eosinophilic myositis, eosinophilic fasciitis; cancers with leukocyte infiltration of the skin or organs. Other diseases or conditions in which undesirable inflammatory responses are to be inhibited can be treated, including, but not limited to, reperfusion injury, atherosclerosis, certain hematological malignancies, cytokine-induced toxicity (e.g., septic shock, endotoxic shock), polymyositis, dermatomyositis. Infectious diseases or conditions of human or other species which can be treated with inhibitors of chemokine receptor function, include, but are not limited to, HIV.

Diseases or conditions of humans or other species which can be treated with promoters of chemokine receptor function, include, but are not limited to: immunosuppression, such as that in individuals with immunodeficiency syndromes such as AIDS or other viral infections, individuals undergoing radiation therapy, chemotherapy, therapy for autoimmune disease or drug therapy (e.g., corticosteroid therapy), which causes immunosuppression; immunosuppression due to congenital deficiency in receptor function or other causes; and infections diseases, such as parasitic diseases, including, but not limited to helminth infections, such as nematodes (round worms); (Trichuriasis, Enterobiasis, Ascariasis, Hookworm, Strongyloidiasis, Trichinosis, filariasis); trematodes (flukes) (Schistosomiasis, Clonorchiasis), cestodes (tape worms) (Echinococcosis, Taeniasis saginata, Cysticercosis); visceral worms, visceral larva migraines (e.g., Toxocara), eosinophilic gastroenteritis (e.g., Anisaki sp., Phocanema sp.), cutaneous larva migraines (Ancylostona braziliense, Ancylostoma caninum). The compounds of the present invention are accordingly useful in the prevention and treatment of a wide variety of inflammatory, infectious and immunoregulatory disorders and diseases.

In addition, treatment of the aforementioned inflammatory, allergic and autoimmune diseases can also be contemplated for promoters of chemokine receptor function if one contemplates the delivery of sufficient compound to cause the loss of receptor expression on cells through the induction of chemokine receptor internalization or delivery of compound in a manner that results in the misdirection of the migration of cells.

In another aspect, the instant invention may be used to evaluate the putative specific agonists or antagonists of a G protein coupled receptor. The present invention is directed to the use of these compounds in the preparation and execution of screening assays for compounds that modulate the activity of chemokine receptors. Furthermore, the compounds of this invention are useful in establishing or determining the binding site of other compounds to chemokine receptors, e.g., by competitive inhibition or as a reference in an assay to compare its known activity to a compound with an unknown activity. When developing new assays or protocols, compounds according to the present invention could be used to test their effectiveness. Specifically, such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving the aforementioned diseases. The compounds of the instant invention are also useful for the evaluation of putative specific modulators of the chemokine receptors. In addition, one could utilize compounds of this invention to examine the specificity of G protein coupled receptors that are not thought to be chemokine receptors, either by serving as examples of compounds which do not bind or as structural variants of compounds active on these receptors which may help define specific sites of interaction.

The weight ratio of the compound of the present invention to the second active ingredient may be varied and will depend upon the effective doses of each ingredient.

Generally, an effective dose of each will be used. Thus, for example, when a compound of the present invention is combined with an NSAID the weight ratio of the compound of the present invention to the NSAID will generally range from about 1000:1 to about 1:1000, or alternatively from about 200:1 to about 1:200. Combinations of a compound of the present invention and other active ingredients will generally also be within the aforementioned range, but in each case, an effective dose of each active ingredient should be used.

The compounds are administered to a mammal in a therapeutically effective amount. By “therapeutically effective amount” it is meant an amount of a compound of the present invention that, when administered alone or in combination with an additional therapeutic agent to a mammal, is effective to prevent or ameliorate the thromboembolic disease condition or the progression of the disease.

DOSAGE AND FORMULATION

The compounds of this invention can be administered in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. They may also be administered in intravenous (bolus or infusion), intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts. They can be administered alone, but generally will be administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.

The dosage regimen for the compounds of the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient, and the effect desired. A physician or veterinarian can determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the thromboembolic disorder.

By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to 1000 mg/kg of body weight, or between about 0.01 to 100 mg/kg of body weight per day, or alternatively, between about 1.0 to 20 mg/kg/day. Intravenously, the doses will range from about 1 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.

Compounds of this invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using transdermal skin patches. When administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices.

For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like.

The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.

Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxide-polylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels.

Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 100 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition.

Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract.

Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration may contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.

Representative useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:

Capsules

A large number of unit capsules can be prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.

Soft Gelatin Capsules

A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil or olive oil may be prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules should be washed and dried.

Tablets

Tablets may be prepared by conventional procedures so that the dosage unit is 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.

Injectable

A parenteral composition suitable for administration by injection may be prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution should be made isotonic with sodium chloride and sterilized.

Suspension

An aqueous suspension can be prepared for oral administration so that each 5 mL contain 100 mg of finely divided active ingredient, 200 mg of sodium carboxymethyl cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol solution, U.S.P., and 0.025 mL of vanillin.

Where the compounds of this invention are combined with other anticoagulant agents, for example, a daily dosage may be about 0.1 to 100 milligrams of the compound of the present invention and about 1 to 7.5 milligrams of the second anticoagulant, per kilogram of patient body weight. For a tablet dosage form, the compounds of this invention generally may be present in an amount of about 5 to 10 milligrams per dosage unit, and the second anti-coagulant in an amount of about 1 to 5 milligrams per dosage unit.

Where two or more of the foregoing second therapeutic agents are administered with the compound of the present invention, generally the amount of each component in a typical daily dosage and typical dosage form may be reduced relative to the usual dosage of the agent when administered alone, in view of the additive or synergistic effect of the therapeutic agents when administered in combination. Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material which effects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.

These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.

While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
